Abstract
Background: Evaluating responsiveness and calculating minimally important change (MIC) for the Persian-version
of the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire following physiotherapy in patients with lateral
elbow tendinopathy (LET).
Methods: We enrolled 82 patients with LET to complete the PRTEE. After completing four weeks of physiotherapy,
all patients were reevaluated by the PRTEE. The patients also rated their changes on a 7-point global rating of change
scale (GRoC). The receiver operating characteristic (ROC) curve and correlation analysis were used for evaluating the
responsiveness. The MIC was determined by determining a desirable cutoff on the ROC curve.
Results:The results showed a moderate relationship (Spearman’s correlation coefficient= 0.43-0.56) of total PRTEE,
pain subscale, and function subscale with the GRoC scale. The total PRTEE, pain subscale, and function subscale
revealed an area under the curve of 0.87, 0.82, and 0.83, respectively. We found the MICs 31.33, 14.5, and 15.5 points
for total PRTEE, pain subscale, and function subscale, respectively.
Conclusion: The Persian-version of the PRTEE questionnaire has acceptable responsiveness and can measure
changes in patients with LET following physiotherapy. We advocate using the PRTEE questionnaire in both clinical
settings and research.
